Manchester United have opened talks with Manchester City over twins Tyler and Jack Fletcher.
The 16 year-old midfielders are the sons of United technical director Darren Fletcher.
The pair do not turn 17 until March, when they can sign pro terms, but discussions are underway between the two clubs about a move to Old Trafford for the pair, says the Manchester Evening News.
Fletcher is said not to be involved in United's pursuit.
Both players qualify for England and Scotland and are rated highly by City management.
A source close to discussions said: "The United academy has monitored Jack and Tyler for a number of years and made a preliminary approach to City last week to open discussions.
"It is still at a really early stage so you never know what will happen. Neither of the boys have signed scholarship terms yet so they are at the stage when they can explore their options.
"As junior internationals, they are amongst the most talented U16s players in the United Kingdom so United are naturally interested in adding them to an already strong age group.
"Obviously Darren would normally be key to this type of recruitment but his only involvement on this occasion has been purely as a father supporting his children.
"Despite their age, both of the boys are really mature and strong-willed so Darren has completely stepped back to enable them to make the best decision for their future careers."
